DOI: 10.1007/s41980-021-00603-w
Abstract: Using a classical Cauchy integral argument, we obtain sharp-weighted inequality for mth order commutator of a square function with $$b \in \text{ BMO }$$ . Also, the $$A_{p}-A_{\infty }$$ estimate for commutators of square functions… read more here.

DOI: 10.1103/physrevlett.129.260402
Abstract: The modular commutator is a recently discovered entanglement quantity that quantifies the chirality of the underlying many-body quantum state. In this Letter, we derive a universal expression for the modular commutator in conformal field theories… read more here.

DOI: 10.1142/s0219498817501067
Abstract: We propose a new, widely generalized context for the study of the zero-divisor type (annihilating-ideal) graphs, where the vertices of graphs are not elements/ideals of a commutative ring, but elements of an abstract ordered set… read more here.

DOI: 10.11650/tjm/190204
Abstract: Recently, Lenzmann and the author observed how to obtain a large class of sharp commutator estimates by a combination of an integration by parts, an harmonic extension, and trace space estimates. In this survey we… read more here.

DOI: 10.1515/ms-2017-0339
Abstract: Abstract In this note we will prove that the trace of a commutator of the discrete Cesáro operator and a compact operator is zero when the commutator belongs to the trace-class. read more here.
